you might be saying im not new cause im a 3rd dan, but i pretty much suck at the game, so u could say im a newbie but i really came to see if someone could teach me how to parkour....
Welcome! There isn't really a tutorial of "how to parkour". You need to learn to run, jump and trick. To improve those you need to practice, there's some videos to you learn a bit about running and jumping.
Oooh, don't forgot Mocucha's freerunning and sparring tutorials. Both cover very important aspects to learn if you want to get into anything like parkour or tricking.
